Keyboard input?

Since Tic is fantasy computer and not fantasy console like Pico, could we have keyboard input as an option? Would be useful for more advanced games such as sims or RPGs - things that can't reasonably be controlled with two buttons and d-pad or mouse only. Also it would be swell if you could in input tag declare more than one input method if the don't conflict using plus sign (e. g. if you want your game to use both joystick and mouse, enter joy+mouse or mouse+joy. Obviously if keyboard support is added, it would conflict with joystick due to arrows and z/x being part of the keyboard so kb+joy wouldn' t be possible (in keeping with fantasy hardware thing, you could explain that keyboard connects to the same port joystick does and as such the two can't be used together).
